// THE FULL RUNDOWN

If you’re looking to take your Jeep to the next level, this heavy-duty Crawler Coilover system is a game changer. It swaps out all eight link arms for extended-length units, perfect for those aggressive off-road adventures, while still keeping it comfortable on the pavement. You’ll appreciate how the links are mounted high on the frame, giving you that extra ground clearance you need when you're navigating rocky trails. One of the standout features is the Fabtech 5 Ton Joints that the large link arms pivot on. These aren’t just for show—they offer reliability and a surprisingly quiet ride, plus they come with a lifetime warranty. And let’s be honest, nobody wants to get stranded out there. The system includes robust 1/4" thick steel Track Bar brackets that you’ll need to weld on, ensuring your Track Bars are properly relocated for optimal roll center both front and rear. This setup is built to last, so you can focus on the trail ahead without worrying about failure. Now, let’s talk about the front Dirt Logic 2.5 Coilover conversion. This bad boy gives you outstanding high-speed damping, which is fantastic when you’re cruising, but it also excels at low-speed crawling—perfect for those gnarly rock gardens. The coilover is positioned right over the centerline of the axle, which helps prevent premature bushing wear and keeps your handling tight. With dual-rate coil springs, you get the factory load capacity but with a ride quality that feels smooth as butter. The flexible coil design also means you’ll enjoy extended travel for those aggressive rock crawling sessions while still maintaining great manners on the highway. The kit includes 8 Long Arm Links & Mounts, a Coilover Hoop Kit for the front, Long Travel Rear Coil Springs, and Track Bar Brackets for both front and rear. You’ll also get Sway Bar Links, a Pitman Arm, and brake lines for both the front and rear. Plus, there are E Brake Brackets and Rear Bump Stop Brackets to round it all out. The front features Dirt Logic 2.5 Coilovers with reservoirs, while the rear comes with Dirt Logic 2.25 Shocks, also with reservoirs. It’s a solid setup that’s ready to tackle whatever you throw at it. This system is designed for the 2007-2018 Jeep JK 4-Door, so if you’re rolling with those specs, you’re in luck. Just keep in mind that some tire sizes and wheel combinations will require minor trimming, especially if you’re running 35s or 37s. And don’t forget, installation does require some welding, and if you’ve got a 2012-2018 model, you’ll need to modify the exhaust too. But trust me, the payoff is worth it when you’re out there conquering the trails.
